Last week, the Skomer Island Project team returned to Skomer to undertake the latest phase of archaeological research on the Island. This year archaeologists Louise Barker and Toby Driver (RCAHMW), Bob Johnston (University of Sheffield) and Oliver Davis (Cardiff University) were delighted to be joined by geographer and environmental scientist Sarah Davies of Aberystwyth University.

The aims of this year’s work were twofold; to excavate one of the Island’s main archaeological features, a prehistoric field boundary and the continuation of geophysical survey within the improved fields surrounding the old farm in the centre of the Island.

Despite Storm Katie cutting short our planned four days of fieldwork, we managed to achieve our goals in the two sunny and still days we had and were also lucky enough to witness the return of the puffins.

The focus of our small evaluation trench was a substantial lynchet, part of the Northern Field Systems on the Island. A lynchet is a bank of earth that builds up on the downslope of a field ploughed over a period of time and the resulting earth or plough soil is important for helping us reconstruct the environmental history of the Island, identify what was being cultivated and possibly at what date. Therefore, the principal focus of the excavation was to recover samples of the soils within the lynchet which will now be carefully analysed over the coming months.

Preliminary results from the geophysical survey also look positive. Within the improved fields surrounding the farm in the centre of the Island, there is little evidence for surviving archaeology; however geophysics undertaken in 2012 did reveal sub-surface archaeological features and we wanted to see if this was the case elsewhere. This was indeed the case, and in the area surveyed directly to the west of the farm, the gradiometer detected a linear feature, perhaps a ditch cut by later cultivation ridges.
